LATRINEAND WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 284,976, datedSeptember 11, 1883.

Application filed April To all whom, iin/tay concern:

vtrated.

Be it known that I, VALTER E. PARFITT, of Brooklyn, Kings county, NewYork, have invented certain new and useful Improvements in Latrines andWater-Closets, of which the following is a specification.

My invention relatesmore especially to what are known as latrines7-thatis, elongated waterclosets having a common receivingchamber orwater-trough over which a number of seats are tted, and discharging atone end into the sewer, such as adapted for schools, barracks, andpublic places. My invention, however, is also adapted for ordinary orsingle water-closets when `so desired; and it consists in the peculiarconstruction, arrangement, and combination of parts, as hereinafter morefully described and claimed. Y

Figure l of the annexed drawings presents a longitudinal section of myimproved latrine, and Fig. 2, a plan view thereof, shown partly insection, on the line x a: of Fig. l.

In these figures, a a indicate the receivingchamber of the latrine,which has the usual shape of an elongated water-trough, as shown, and ismade of Isheet-lead, as represented in the drawings, supported in andinclosed by a wooden frame or casing,b b. The trough or body of thelatrinemay, however, be made`of hydraulic cement, or of brick or iron,or of any other suitable material, as will be readily understood byarchitects, plumbers, and other experts.

Over the receiving-chamber a is arranged the seat or cover c, which ispreferably hinged to lift up, as usual, and is provided with a number ofindividual openings, as shown, more or less, according to the length ofthe latrine. At the initial end of the receiving-chamber is aflushing-chamber, d, containing ,the flushing devices, as hereinafterdescribed, and this end of the chamberhas an inclined base, e, asillusrlhe terminal end of the receivingchamber has also an inclinedbase, which forms a dam or Weir, f, of limited depth, adjacent to whicha free discharge outlet or neck, g, opens, and into which the waterrunning over the dam escapes freely to the sewer, asuitable trap beingof course arranged between thev discharge-neck g andthe sewer, as willbe underv stood.

into this receiving-chamber extend the waterpipes 1J k, arranged todischarge directly into the tank m, so as to charge the same eitherconstantly or intermittently. The larger pipe, i, may connect with therain-leaders from the roof, or with waste-pipes from the several sinksand wash-basins of the house, or with bathtubs, so as to convey all therain and waste water to the latrine, and thus serve to utilize the samefor more cffectually iiushing the latrine. I prefer, however, inallcases to provide a smaller pipe, lf, to convey a constant andindependent supply of fresh water from the regular water-service pipesto the flushingtank. This pipe is provided with a cock, n, which may beadjusted to deliver a constant stream into the tank on, and of greateror less volume, according to the size or extent of use of the latrine,as will be understood.

A door, o, in the side of the flushing-chamber permits access to theseveral parts for examination or adjustment, which may be afterwardclosed and locked, to prevent mischievous tampering with the mechanism.

The iiushing-tank m is preferably provided `with short trunnions p oneach side, near its center of gravity, which trunnions pivot on socketplates or ears r r, affixed to opposite sides ofthe fiushing-chamber, asshown best in Fig. 2. The flushing-tank is thus capable of being freelyturned on its pivots and dumped in the chamber, as indicated lby dottedlines in Fig. 1; but the tank is so weighted that when empty, or nearlyso, it will always 'assume an upright position, as indicated by fulllines in Fig. l, where its mouth will underlie the water -pipes i k andreceive the water therefrom, as illustrated; It will be noted, however,that the upper part of the tank has greater capacity on one side of thepivot-line-that is, on the side toward the discharge end of the latrine.Consequently when the tank becomes filled nearly to the top the tankbecomes overbalanced and automatically tips or dumps, as indicated bydotted lines in Fig. 1, thus suddenly discharging a large mass of waterinto the water -trough or receiving-chamber a,

which -produces an energetic surging wash therein, and causes a wave tosweep toward the discharge end, carrying the soil or other mathas dumpedits charge of water, it will of course immediately rise to receive afresh charge, after which the same operations will be repeated atregular intervals and more or less frequent, according to the volume ofwater flowing from the pipes z' k, thereby cleansing the latrine in amanner which is perfectly automatic, and at the same time certain andAvThis system, as will be readily noted, i

simple. is .both economical in the vuse of water and energetic in thecleansing action, for, obviously, a volume of water discharged suddenlyin a mass at intervals into the receiving-chamber will produce a morethoroughand certain cleansing action than would a larger volume of waterif allowed to ilow continually throughl the chamber.

It will be noted on reference to Fig. l that each end of thewater-trough is inclined, the incline at the discharge end forming thedam f, and the incline at the initial end being just below the tank m.By this means the mass of water is of wedging form at each end, and isthus easier set in motion. Consequently when the tank m is dumped, themass of water being suddenly precipitated upon one end of the wedge,tlie whole mass moves easily and in a powerful wave toward the oppositeend, where the wave easily rides over the inclined dam f andprecipitates itself, together with the oating soil, into the dischargeg, thus rendering the action `easy, quick, and energetic.

I do not wish to infer any broad claim to an automaticallytiltingordumpingflushing-tank, in combination with the receiving-chamber ofwaterclosets or like structures, as several former instances of such anidea can be given. In all such eases, however, the tank has dumped intoan ordinary form of water-closet bowl with inclining sides and with afree discharge-outlet at or about its center, whereas in my case thereceiving-chamber is an elongated trough with a shallow dam at one endand a free discharge-outlet` adjacent thereto, and at the opposite endis arranged the dumping-tank. By this construction a limited depthofwater always remains in the trough and the excess freely lows over theterminal dam into the free discharge-outlet, while the intermittentdumping of the flushing-tank in the opposite end of the trough causes apowerful wave or surging action of the water from the initial to theterminal end of the trough, which causes all deposits to` be sweptenergetically over the dam and dashed into the outlet, whereby a veryeffective cleaning action is produced, and which presents a greatlyimproved form of latrine.

I am also aware that a sewer-vault has been provided with anautomatically tilting or dumping flushing-tank, as shown in the patentof Dark, No. 91,828, of January 29, 1869; but

in this case the dumping-tank was placed outside and remote from thevault, and arranged to dump into a funnel-pipe which led into one end ofthe vault. The vault or watentrough was not inclined at each end, andthe parts were not arranged so as to secure the energetic wave actionfrom one end of the trough to the other over the terminal dam, for inthis case the trough did not have a free dischargeoutlet over the dam atthe terminal end, for a partition, g, depended down into the water infront o'f the dani, forming a trap or water-seal, so that the wave,rwhich would in my case sweep freely over the dam and carry with` it allfloating matter, would in this reference be obstructed by the pendentsealing-partition and have no such eifect.

What I claim isl. A latrine having its water-trough inclined at eachend, with a free discharge-outlet beyond the incline, a dumping-tankpivoted directly above the incline at the initial end, a feeder forsupplying water to said dump-tank,

and a water-pipe for supplying water continuhaving valve n, all combinedand adapted to serve, in relation to the cover c and outlet g, as setforth.
